Abstract (en)
[origin: WO2011046654A1] An LED (light emitting diode) illumination device that can generate a uniform light output illumination pattern. The illumination device includes an array of LEDs, each having a LED central axis. The LED central axis of the array of LEDs is angled approximately toward a central point. The illumination source includes a reflector with a conic or conic-like shape. The reflector wraps around the front of the LED to redirect the light emitted along a LED central axis.
